My teacher showed our class how to find the graph of a derivative using tangent lines. I can not figure this out.
I would really appreciate it if someone could help me or explain it to me.
Thank you very much for your help.
The slope of a straignt tangent line at any point of a y(x) curve is the derivative of the y(x) function at that point.
To get the derivative this way, you would have to draw a series of tangent lines at diffent points of the curve, measure the slope of each line, and replot the derivative function (slope vs. x) using those measured points.
Thank you very much, drwls.
I actually understand it now!
